Question

Solve : $\sqrt{1\frac{4}{5}\times 14\frac{21}{44}\times 2\frac{7}{55}}$

Answer 1

$\sqrt{1\frac{4}{5}\times 14\frac{21}{44}\times 2\frac{7}{55}}=\sqrt{\frac{9}{5}\times \frac{637}{44}\times \frac{117}{55}}$

$=\frac{3\times \sqrt{637\times 117}}{12100}$

$=\frac{3\sqrt{74529}}{110}$

$=\frac{3\times 273}{110}=\frac{819}{110}$
